STEVAL-IHM036V1: 100W, 3Ph PMSM Sensorless Driver, 195 ~ 265VAC in

This document describes the low power motor control board STEVAL-IHM036V1 featuring the SLLIMM™ (small low-loss intelligent molded module) STGIPN3H60 and MCU STM32F100C6T6B. The demonstration board is an AC/DC inverter that generates a 3-phase waveform for driving 3-phase permanent magnet synchronous motors (PMSM) with field-oriented control (FOC) up to maximal 100 W without sensors. The used controller belongs to the STMicroelectronics™ ARM® Cortex™-M3 core-based medium density STM32™ MCU family.

The main device presented in this user manual is a universal, fully evaluated and populated design consisting of a 3-phase inverter bridge based on the 600 V IGBT power module in NDIP-26L package. The IGBT power module integrated all power IGBT switches with freewheeling diodes together with the high voltage gate drivers. Thanks to this integrated module, the system has been specifically designed to achieve power inverter in a reliable and compact design. Such integration saves PCB space occupation and assembly costs together with high reliability due to the design simplicity.

The board is designed to be compatible with single-phase mains for the European range of supply voltage 230 VAC (+/- 15%), or corresponding DC supply voltage. The board includes a power supply stage with VIPer™16 in buck configuration to generate +15 V supply voltage required by the application.
